Usually publishers give you attention if you've actually finished writing the book. Or have an agent, which one usually gets after having actually finished writing the book.

I have interest from a publisher right now, I was just trying to have a base of something to show to them. They've signed me so far to finish this book, and then if it does well enough they want me to finish the last two.

This is my second book so far, and the first did okay enough to pay for itself, but not much more, just exploring different things this time around to maximize how much it gets seen!
